1 May 1990 Electrostatic master proofing using photopolymer images
Author Affiliations +
An electrostatic imaging system using permanently imaged photopolymers as printing masters is being developed for producing multiple copies of four color proofs with high productivity and consistency. The imaging element - the master film, is based on electrical conductivity change induced by photopolymerization. After corona charging, the electrostatic latent images are developed by liquid toners and the toner images transferred to a receptor in sequence to yield a color proof. The original photopolymer images may be re-used to produce multiple copies by repeating the charging, toning and transfer steps.
